Driving
Restarting the engine (START mode)
The engine automatically restarts as soon as
the driver indicates the intention of moving off
again, with the clutch pedal fully pressed.
Driving with under-inflated tyres, particularly
in adverse conditions (heavy load, high
speed, long journey):
Overspeed alert
An audible overspeed alert is triggered
when the vehicle exceeds predefined speed
thresholds.
– worsens road-holding.
– lengthens braking distances.
– causes premature wear of the tyres.
– increases fuel consumption.
Special cases
When the vehicle speed is greater than 80
km/h, the alert is emitted once in 2 minutes if
the vehicle speed is maintained at 80 km/h.
When the vehicle speed is greater than 120
km/h, the alert is emitted every 2 seconds.
The engine will restart automatically if the
conditions for operation are met again and in
the following cases:
– Vehicle speed exceeds 5 km/h.
– Some specific conditions (braking assistance,
air conditioning setting, etc.).
The inflation pressures defined for the
vehicle can be found on the tyre
pressure label.
For more information on the Identification
markings, refer to the corresponding
section.
This system cannot be modified nor
deactivated.
In these cases, this indicator lamp flashes
for a few seconds, then goes off.
Under-inflation detection
Malfunctions
Checking tyre pressures
This check should be done when the
tyres are "cold" (vehicle stopped for 1 hour or
after a journey of less than 6 miles (10 km) at
moderate speeds).
Otherwise, add 0.3 bar to the pressures
shown on the label.
This system automatically checks the pressures
of the tyres while driving.
In the event of a malfunction, the button’s
indicator lamp flashes briefly, then remains on.
Have it checked by a CITROËN dealer or a
qualified workshop.
It compares the information given by the wheel
speed sensors with reference values, which
must be reinitialised every time the tyre
pressures are adjusted or a wheel changed.
The system triggers an alert as soon as it
detects a drop in the inflation pressure of one
or more tyres.
The vehicle stalls in STOP mode
All of the instrument panel warning lamps
come on if there is a fault.
►ꢀ Switch off the ignition then start the engine
again.
Under-inflation alert
It is signalled by the fixed illumination of
this warning lamp.
Under-inflation detection does not
replace the need for vigilance on the
part of the driver.
This system does not avoid the need to
regularly check the tyre pressures (including
the spare wheel) as well as before a long
journey.
12 V battery
In addition, the following information is given in
the instrument panel:
When one tyre is deflated then the
corresponding tyre is blinking.
When more than one tyre is deflated then the
four tyres are blinking.
The Stop & Start system requires
a 12 V battery of specific technology and
specification.
All work must be carried out only by a
CITROËN dealer or a qualified workshop.
